1 Claim.

This invention relates to an oar lock sleeve for an oar comprising a hollow cylinder of resilient material.

A primary object of this invention is to provide 7 sleeve being simply slid down over one end of the oar to a position intermediate the ends thereof, after the oar lock has beenflrst mounted on the sleeve. t

Another object of this invention is strengthen and reinforce the oarat the point where oars are likely to break, and it should also be noted that the sleeve will fit snugly on the car so as to prevent moisture from reaching this portion of the oar, thus tending to prevent rot of this portion and consequent breakage.

Still another object of this invention is to pro-' vide an oar lock sleeve which is easily transferable from a broken oar to another oar, and whichmay be adjusted to suit the need of an individual user by sliding the sleeve along the shank of the oar.

Still another object of this invention is to provide the oar lock sleeve with a pair of external radially extending flanges on each end thereof to prevent the sleeve from slipping out of engagement with the car lock, and also providing a more positive mounting for the oar on the boat.

Yet another object of this invention is to provide an car look sleeve whichmay be used with both metal and wooden oars and which is constructed of resilient material so that the operation of the car will be rendered more quiet.

And a last object to be mentioned specifically is to provide an oar lock sleeve which is relatively inexpensive and practicable to manufacture, which is simple and safe as well as convenient to use, and which will give generally eiiicient and durable service.

With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be hereinafter described in detail in the specification, particularly pointed out in the appended claim, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a side elevational view of an car with this oar lock sleeve applied thereto.

Figure 2 is a three dimensionalview of a portion of an oar, an oar lock, and a sleeve according to this invention operatively connected therewith; and

Figure 3 is a vertical sectional view taken through the car lock sleeve and showing a contiguous portion of an oar within the sleeve. 7

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the differ ent views in the drawing.

Referring now to the drawing in detail, this invention is adapted to be used with an environment including an'oar which will have a shank portion 10 and. a blade [2. The oar lock sleeve comprises a hollow cylinder of resilent, compressible rubber or other suitable material indicated at l4. An oar lock [6 having a depending integral pivot pin [8 is used with this invention and may be considered an element of this invention cooperating with the oar lock sleeve and the car. The hollow cylindrical portion I4 is :provided with a pair of external radially extending flanges 20, one on each end of the portion 14,

' these flanges 20 serving as reinforcing members and also serving to prevent the oar look It from slipping out of engagement with the sleeve, during the use of the invention.

The operation of this invention will be clearly understood from a consideration of the foregoing description of the mechanical details thereof, taken in connection with the drawing and the above recitation of the objects thought to be achieved by this invention. In recapitulation, it may be added that one end portion of the sleeve Mand the respective flange 20 thereon are collapsed to permit the ring [6 to be slipped on said sleeve; which is then forced under tension onto the shank portion I0 of the oar, the final positioning of the sleeve on the car being determined by the particular need of the user of the device. The sleeve M is of a diameter to fit snugly within the ring it. It will be clear that all the objects mentioned above will be accomplished by this invention and further description would appear unnecessary.

Obviously, minor variation .in the construction and proportioning of the sleeve may be resorted to without departure from this invention and the scope of this invention should be determined only as limited by a proper interpretation of the terms used in the subjoined claim.

Having described the claimed as new is:

A bushing for oar locks of the type including a pin anda ring thereon, comprising a collapsible invention, what is sleeve of resilient, compressible material for mounting under tension on the shaft of an oar, said sleeve being of substantial thickness and of a diameter to fit snugly within the ring thereon, and retaining flanges for the ring on the ends of said sleeve, said flanges being insertable through the ring when the end portions of the sleeve are collapsed.
